Spot instances

Hi.

I was wondering if anyone could help describe how Star Cluster behaves with
spot instances.

If I specify a bid price at a certain level, and then the spot price
exceeds that whilst say, a parallel compute job is using those resources,
what will happen? Will the nodes be shut down as the bid price has been
exceeded?

Or is the bid price simply used to start the nodes when the price reduces
to a certain cost level or below?

I am running parallel compute jobs that take a few days to complete a
single job, and hence termination of compute nodes during the job would
cause issues.

However, I would very much like to gain access to the reduced costs of spot
prices, with the obvious chance that I could pay more if the spot price
rose above the fixed price.

Any help would be greatly appreciated.

Kind regards,

Ed Morris.
